ABSTRACT:
A semiconductor memory of the static type employs a pair of cross-coupled driver transistors and a pair of access transistors along with load devices which are punch-through elements resembling short channel MOS transistors without gates. The punch-through elements each have an electrode integral with the drain of one of the driver transistors, and another electrode coupled to a voltage supply. A cell layout of very small size is possible.
